Research, CIM

To tackle many of the problems that several infectious diseases impose, we need a better understanding of the human immune system and immune reactions towards pathogens in humans. Studying functional diversity of the human immune system, in particular dendritic cells (DC) and lymphocytes, is highly prioritized at the Center.

Research objectives

The objectives of the research at the Center can be divided into four main groups:

1. To advance our understanding of the human immune system at a cellular and molecular level

Decades of intense cellular and molecular studies have resulted in the identification of components of the immune system. Studies of the mouse immune system, most particularly through the use of animals with targeted gene inactivation, have permitted linking these components to specific functions in immunity. In spite of this progress, the study of the human immune system has lagged behind that of the mouse. Improvements in technologies and reagents, however, now permit detailed analysis of the human immune system at cellular and molecular levels. Such analyses are crucial for furthering our understanding on how the human immune system combats infectious diseases.

2. To advance our understanding of immune reactions to pathogens in humans, and pathogen escape from immunity

With a clearer insight into functions of the human immune system gained through basic research as well as the development of new techniques, we can now address fundamental questions relating to host immune reactions to human pathogens and strategies employed by pathogens to evade immunity, at a level not previously conceivable. Improved understanding of host immunity to human infection set the stage for development of new intervention strategies such as, e.g., new vaccines.

3. To develop new immunomodulatory prevention and treatment strategies for human infectious diseases

Although many approaches to producing new vaccines have been initiated, systematic evaluation and optimization have proceeded slowly, in part because of factors such as the expense and complexities in advancing new candidate vaccines into phase I/II trials and scientific challenges.

Importantly, techniques for eliciting immunogenicity in new vaccines are lacking and sorely in need of complementary, safe adjuvants to help them reach full potential. Likewise, antigens must be optimized to yield the strongest possible immune responses. Vaccine-oriented projects focus particularly on optimizing strategies for HIV vaccination. However, several efforts presented here are equally applicable to vaccines against other major pathogens, e.g., HCV, influenza virus, and M. tuberculosis.

4. To test new immuno-modulatory prevention and treatment strategies in clinical phase I/II trials.

The 21st century has witnessed a need to move research results more quickly to clinical settings. Clinical research helps to assure that new diagnostics, treatments and intervention strategies are safe and effective. Currently, this is a lengthy and sometimes (if not often) inefficient process. Meeting these demands requires new and more efficient processes from discovery to clinical validation of research results in humans. Current clinical trials planned involves testing one new HIV vaccine concept and one new Tuberculosis vaccine concept. Studies are also going on aiming at developing adoptive immunotherapy protocols with NK cells against specific malignancies.
